Abstract :
Due to the presence of a high-frequency LC tank circuit, dynamics of a resonant converter are unpredictable, often with large surge of tank energy during transients. Employing state-plane analysis technique, a novel “optimal trajectory control” utilizing the desired solution trajectory as the control law has been previously proposed for the series resonant converters. The method predicts the fastest response possible with minimum energy surge in the resonant tank. The principle of the control and its experimental implementation are described. The dynamics of the converter are shown to be close to time-optimal.
